Two superbosses remained, NG+ or not?
I cleared most of the superbosses in challenge mode, except 1) Immovable Heir Carlos (the lv150 ape), 2) Ardainian Kurodil (lv 130 dinosaur). Most of the tutorials found online assume you have three accessory slots + max hidden affinity chart so that you can deal insane damage to finish the challenge before the boss uses powerful Art to one shot your entire party. Is it possible to beat these two challenges without entering New Game Plus?
For Kurodil, I basically have an idea. Dodge the Doom effect and Ultra Annihilation Flare by Chain Attack or Blade Combo Finisher. However, due to its high HP and 80% reduced Ether damage, the battle took too long so I didn't try too hard on this one. (Never want to have a 40min+ battle again after Elma Redux)
For the fxxking ape, if Chain Attack cannot finish him, after Chain Attack it uses one-shot Art immediately to wipe out the whole party (700+ Agility S+ Mythra also got hit). It also has Doom, Party Meter drain, high HP, etc.; all sorts of disgusting stuff combined together. If using a common Blade with Orb Master, how to keep the common Blade character surviving long enough to attach 5 orbs on the ape becomes a big issue.
I will eventually play NG+ for sure, but just for experiencing the main story again, and don't want to farm anything. (I basically have everything farmable already, except for lv6 Aux Cores for every blade.) Just these two challenges become a thorn in the throat. Should I try harder now, or copy Enel's build in NG+ to destroy them (after obtaining Zeke)?
---------------------------------------
Edit: I managed to beat the Kurodil. Party:
Rex (Mythra + two support blade (agility weapon/mod, hunter chemistry + orb ender), dauntless boots + avant-garde medal for survivability),
Morag (Dagas + Corvin, Aff Max ATK + Crit Up + Titan Hunter, burst symbol + avant-garde medal),
Tora (QTPi according to Enel's tutorial setup, change Vedentta to Titan Hunter, earth element; QT (or Alpha) in water element (light light water combo is pretty fast), Master Scope + burst symbol)
Pouch item: Glarna Stir-Fry + Fish and Herb Broth, sold in Challenge Land. (0.4+0.4 Art recharge)
Basic idea: Use Mythra level 2 AOE special to clear the mobs ASAP (Wave 3 sniper needs to be eliminated immediately), for the Korodil fight, use driver combo (QTPi break, Rex topple, QTPi launch, Corvin smash) to interrupt Kurodil. Use chain attack / blade combo finisher / LV4 special to dodge Doom and Ultra Annihilation Flare. Two small chain attack (1-2 orbs) should take him down.
Only ONE APE to go.
----------------------------------------------
Edit 2: THE APE is down.
Similar setup, change Rex's dauntless boots to Omega Drive (for faster chain attack, agility doesn't help too much for lv150 boss), Morag's burst symbol to Omega Drive; Aux core change to Beast Hunter.
Basic idea: when it uses Venom Cloud (Doom), chain attack; when it enters enraged mode and uses Wild Wave (party wipe attack), chain attack. Don't chain attack if there is no threat. (especially near its 65% HP (enraged threshold)) Because of two Omega Drives (and moon matter chips on everybody), the Party Gauge replenishes extremely fast, which neutralizes all its ridiculous Arts.
BTW, remember to bring Fiora for this fight to max her affinity chart. Otherwise her node won't complete. (Same for Elma on Kurodil's fight, had to beat that one again.)
